Setup Guide — MDA 5V, 5SV, 5A RCA The Extron® MDA 5 series of mini distribution amplifiers distribute buffered composite video (MDA 5V), buffered S-video (MDA 5SV), and amplified stereo audio (MDA 5A RCA). Unless otherwise stated, these instructions apply to all three of the amplifiers. W These instructions provide a quick setup guide for experienced installers. Installation and service must be performed by authorized personnel only.

Step 2 Mount the unit in a convenient location, in a rack, under a desk, or on a projector mounting system. Follow the instructions included with the appropriate mounting kit. Step 3 Connect the external 12 VDC power supply (provided) to the 2-pole, captive screw power connector (b). When power is applied to the unit, the front panel LED (a) lights green. C Voltage polarity is important. Identify the negative lead by the ridges on the side (see figure at right). C Always use a power supply specified by Extron for this unit. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the distribution amplifier. Step 4 For the MDA 5V: Connect a video source to the video input (c), using composite video (BNC) connectors. For the MDA 5SV: Connect a video source to the video input (c), using S-video (4-pin mini DIN) connectors. For the MDA 5A RCA: Connect an audio source to the audio inputs (c), using unbalanced stereo to RCA connectors. Left channel input goes to the upper input; right channel input goes to the lower input.
